I could only find a 9 volt AC transformer where the machine says it takes a 12 volt DC power supplyI plugged it in and it worked but I didn't run it for more than a second in fear of what would happenWould it be okay to run the machine this way?
In theory no, I'm surprised it worked at allIt must have diode protection from reverse phase connections so the 9 volts AC got rectified into DC by thatI wouldn't have tried it the first time and you probably shouldn't try it againYou could connect the 9 volt AC to a full wave bridge rectifier from Radio Shack and a filter capacitor and make it work but if you are going to Radio Shack anyway you might as well pick up a 12 volt DC power supplymk
